OPTICAL ILLUSIONS

Page 4: Optical illusion

The ‘brown’ square in the centre top, and the ‘orange’ square in the centre front are exactly the same shade of brown.

Don't believe it?

Page 5: Optical illusion

Are the two circles the same colour?

Page 6: Optical illusion

Which part of the picture is darker – left or right side?

Page 7: Optical illusion
Page 8: Optical illusion

What do you see?

Page 9: Optical illusion

Do you see a ‘floating triangle’?

Page 10: Optical illusion

Are the linesparallel?

Page 11: Optical illusion

Totally straight lines?

Which is larger – the left or right hand card?

The SCINTILLATING GRID – black dots appear at random intersections

Focus on a single intersection, the dot does not appear. The dots disappear if you are too close or too far from the image.

Page 15: Optical illusion

Move your head back and forward.

What happensto the

circles?

Page 16: Optical illusion

Focus on just the centre circle

while moving your head

Page 17: Optical illusion

How many circles

can you see?

Did you see the 16 circles?

Page 18: Optical illusion
Page 19: Optical illusion

If your eyes follow the movement of the rotating pink dot,

the dots will remain only one color, pink.

However if you stare

at the black " +" in the center, the moving dots turns to green.

Now, concentrate on the black " + " in the center of the picture. After a short period, all the pink dots will

slowly disappear, and you will only see only

a single green dot rotating.

Look at the wildlife painting of a Bengal tiger.

Can you find the hidden tiger in the picture?

Page 24: Optical illusion

“the hidden tiger” is written in the tiger

Page 25: Optical illusion

The "illusion" is that this is just a picture of coffee beans; but it is not. Can you find a man's face among the beans?

If you find the face in 3 seconds or less, the right half of your brain may be more well developed than most.

What do you see?

In black you can read the word GOOD; but the word EVIL also appears in white letters inside each black letter.

Page 27: Optical illusion

What word can you see?

Page 28: Optical illusion

What do you see?

You may not see it at first, but the white spaces create the word OPTICAL,while the blue landscape spells out ILLUSION

What do you see?

You probably read the word ME in brown, but....... when you look through MEyou will see YOU!

You should see a face ….

Tilt your head to the right – the word begins with L.

This is called an "impossible object," which means that it's impossible to build.

But drawing it is not impossible, as you see in the image.

Julian Beever creates pavement art. Many of his creations are optical

illusions, such as this one, where he appears to be perched on a ledge, waiting for Batman and Robin to

climb the building and rescue him.

In reality, there is just pavement in front of him – the rest is a 'trick the

eye'.

Page 61: Optical illusion

Can you see the Shark in the picture above. The trick is not to focus directly on the image but

try to focus on a point through the image. With a bit of patience and relaxation you CAN do it.

Page 62: Optical illusion

What can you see in the picture above?

Remember the trick is not to focus directly on the image but try to focus on a point through the image.

With a bit of patience and relaxation you CAN do it.
